Versuchsvorschrift

Trifluoroacetic acid (1.0 mL) and thioanisole (100 μl) were added to the resulting quinoline-6-carboxylic acid (5-(3-benzyloxy-phenoxy)-thiophene-2-ylmethyl)-amide (73 mg, 0.156 mmol), and the solution was stirred for 30 minutes at room temperature. The reaction solution was neutralized with an aqueous solution of saturated sodium bicarbonate, then, extracted with ethyl acetate and dried over anhydrous magnesium sulfate. The solvent was evaporated, the residue was purified by NH silica gel column chromatography (ethyl acetate: methanol), and the title compound (47 mg, 80%) was obtained as a colorless solid.
